Crockpot Roast Beef

I found a recipe on Crockpot365 and since I didn't have all of their ingredients I modified it to fit my ingredients.

2 Tbsp A1 Sauce
2 Tbsp Honey Mustard
1/4 cup apple juice
1/2 cup beef broth
Chuck Roast
1 sweet onion
5 carrots (I used Purple Haze carrots from my CSA)
You can throw potatoes in too if you like.

Mix the A1 Sauce, Honey Mustard and Apple Juice. Pour on all sides of the roast (in crock pot). Throw in the chopped onion and the chopped carrots. I cut the carrots into half lengthwise and then thirds. Pour beef broth around roast (not on top). Cook on low for 8-10 hours.
